It would seem, despite being outfitted with the finest flash memory that money can buy, even Mars rover Opportunity isn’t immune to worn-out NAND cells. After a dozen unplanned reboots in August, most likely caused by the faulty flash, NASA is moving ahead with a complete reformat of the rover’s volatile memory. Back in 2004, Opportunity’s sibling rover — Spirit — was brought back from the brink of death with a similar reformatting maneuver. Considering Opportunity has now been roving the surface of Mars for over a decade, and all it has required is some small software updates and now a format, I’d say the little rover has done rather well.
